Add Routing table data to node view

[royrusso]

Should be added as a button next to the "i" icon for node settings information that opens a modal with the information in tabular format.

http://localhost:9200/_cluster/state?filter_blocks=true&filter_nodes=true&filter_metadata=true&filter_indices=true

ie...

routing_nodes: {
unassigned: [ ],
nodes: {
RzcgOdHRSlO3hw5-pVCPMw: [
{
state: "STARTED",
primary: true,
node: "RzcgOdHRSlO3hw5-pVCPMw",
relocating_node: null,
shard: 0,
index: "twitter"
},
{
state: "STARTED",
primary: false,
node: "RzcgOdHRSlO3hw5-pVCPMw",
relocating_node: null,
shard: 2,
index: "twitter"
},
{
